Abstract

A display device includes a display panel and a voltage generating part. The display panel includes a switching element, a main pixel section, a coupling capacitor and a sub pixel section. The main pixel section is electrically connected to the switching element. The coupling capacitor has a first end electrically connected to the switching element. The sub pixel section is electrically connected to a second end of the coupling capacitor. The voltage generating part controls data voltages corresponding to a gray-scale in a range from a low gray-scale to a high gray-scale that corresponds to a saturation voltage of the sub pixel section for displaying an image. The data voltages are applied to the display panel. Therefore, the viewing angle and the luminance are improved.

Description

[0001] This application claims priority to Korean Patent Application No. 2005-05906 filed on Jan. 21, 2005, and all the benefits occurring therefrom under 36 U.S.C. 119, the contents of which are herein incorporated by reference in its entirety. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a display device and an apparatus for driving the display device. More particularly, the present invention relates to a display device for improving a viewing angle and an apparatus for driving the display device. [0004] 2. Description of the Related Art [0005] A liquid crystal display (LCD) device, in general, includes two substrates and a liquid crystal layer inserted between the substrates. In the LCD device, in general, liquid crystal molecules of the liquid crystal layer varies in their arrangement in response to an electric field applied to the liquid crystal layer, and thus a light transmittance of the liquid crystal layer is changed w...
